Step-by-Step Instructions
1. Cook the Pasta
Bring a large pot of generously salted water to a boil.
Add the spaghetti or linguine and cook until al dente according to the package directions.
Before draining, reserve about ½ cup of pasta water. Drain the pasta and set aside.
2. Sear the Steak
Pat the steak cubes dry with paper towels and season with garlic powder, Italian seasoning, smoked paprika, salt, and black pepper.
Heat olive oil in a large skillet over medium-high heat.
Add the steak in a single layer and sear for about 2–3 minutes per side until deeply browned on the outside and cooked to your preferred doneness.
Add 1 tablespoon butter during the final minute, toss the steak in the melted butter, then transfer it to a plate.
3. Cook the Vegetables
Reduce the heat to medium and add the remaining tablespoon of butter.
Add the onion, zucchini, and diced red bell pepper.
Cook for 3–4 minutes, stirring occasionally, until the vegetables are lightly browned but still slightly firm.
Add the minced garlic and cook for another 30 seconds until fragrant.
4. Make the Cream Sauce
Pour the heavy cream into the skillet and stir well, scraping up any flavorful browned bits from the bottom.
Add Italian seasoning and crushed red pepper flakes.
Bring the sauce to a gentle simmer and cook for 3–4 minutes.
Stir in the grated Parmesan gradually until completely melted and the sauce becomes smooth and creamy.
Add reserved pasta water a little at a time until the sauce reaches a silky consistency.
5. Combine Everything
Add the cooked pasta directly to the skillet and toss until every strand is evenly coated in the creamy garlic Parmesan sauce.
Return the steak bites to the skillet along with any juices from the plate.
Gently fold everything together and cook for another 1–2 minutes, just long enough to warm the steak without overcooking it.
6. Serve
Transfer the creamy steak pasta to serving bowls.
Top with fresh parsley, extra Parmesan, freshly cracked black pepper, and red pepper flakes if desired.
Serve immediately while the pasta is hot and the sauce is creamy.
Cooking Tips
- Pat the steak completely dry before cooking so it develops a deep golden crust.
- Avoid overcrowding the skillet; cook the steak in batches if necessary.
- Keep the zucchini slightly firm so it does not become mushy in the cream sauce.
- Freshly grated Parmesan melts more smoothly than pre-shredded cheese.
- Add pasta water gradually to loosen the sauce without making it watery.
Serving Suggestions
Serve this creamy steak and zucchini pasta with:
- Garlic bread or toasted baguette
- Caesar salad
- Roasted asparagus
- Steamed green beans
- Fresh tomato and cucumber salad
Storage
Store leftovers in an airtight container in the refrigerator for up to 3 days.
Reheat gently in a skillet over low heat with a splash of milk, cream, or pasta water to restore the creamy consistency. Avoid overheating the steak, as it can become tough.
Leftover Ideas
- Turn leftovers into a cheesy steak pasta bake topped with mozzarella.
- Add mushrooms, spinach, or broccoli for extra vegetables.
- Chop the steak into smaller pieces and use the pasta as a filling for a creamy baked casserole.
FAQs
What type of steak works best?
Sirloin, ribeye, New York strip, or tenderloin all work well. Sirloin is especially convenient because it is flavorful, tender, and easy to cut into bite-sized pieces.
Can I use another pasta shape?
Yes. Fettuccine, penne, rigatoni, bowtie pasta, or tagliatelle all work beautifully with the creamy sauce.
Can I substitute the zucchini?
Yes. Mushrooms, broccoli, asparagus, spinach, or bell peppers are excellent alternatives.
How do I keep the steak tender?
Sear it quickly over medium-high heat and remove it from the skillet before making the sauce. Return it only at the end so it does not overcook.
